He replaced "The Howard Stern Show" in the morning in June 2004 and his contract was not renewed for financial reasons in 2006. Cox released three CDs while on the air at WXDX-FM Pittsburgh: "Alan Cox Sells Out", "Ribbed", and "Shadyside Bathroom Wall Blues". He frequently performed at numerous comedy clubs throughout the area, and a portion of the proceeds from his CDs were donated to local charities. Cox left in 2006 to host The Morning Fix at WKQX (Q101) in Chicago. Currently, he hosts afternoons at WMMS in Cleveland, Ohio.
• Tim Benz – Co-hosted the weekday morning show from 2006 until February 2014, when he became sports director for all Pittsburgh Clear Channel stations.[6] Benz resigned as sports director in May 2014 to co-host a program on WEEI-FM in Boston with Lou Merloni and Christian Fauria.[7]

Known for antics such as giving away "Oceanfront condominiums in Idaho" on April Fools' Day, she was later recruited to be Program Director and Afternoon Jock at WXDX after the Viacom-Secret Comm-Entercom buy outs. It was this era that WXDX saw its greatest evolution and its on-air staff its greatest growth. In 1997 she moved to Philadelphia to start up and host afternoons for Modern AC-"Max 95.7" WXXM. There she simultaneously hosted the nationally syndicated show "Today's Women" as a "Lilith Fair" radio companion for United Station Radio Networks (a Dick Clark company). Later she directed and oversaw CDNow.com's first forrays into online radio products and stations, which included the company purchase of Napster.com. She later returned to "terrestrial" radio at Adult Alternative WXPN in Philadelphia where she hosted evenings on-air while associate producing syndicated "World Cafe". She also managed the digital relationship the program had with Sirius Satellite Radio and booked all of the artists. After 25 years in Radio and music, she now continues work starting up companies in other industries, consulting and teaching at Temple University.
